Specication of Letters Patent.

Application filed September 23, 1913. Serial No. 791,320.,

To all whom t may concern Be it known that I, MAURICE NEUMAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Tobacco-Pipes, of which the following is a specification.

My present invention relates to tobacco pipes and my object is to provide a pipe embodying certain novel parts, arrangements of parts and adjustments whereby the quantity and temperature of the smoke may be regulated to suit the user, whereby to eliminate in a Great measurethe production of nicotin, ,an whereby certain other' advantages to the smoker may be promoted and attained. These parts, arrangements of parts, and adjustments together with their resulting advantages will be more clearly understood from the following description thereof, reference being made to the accompanying drawing, in which- Figure 1 is a vertical longitudinal section, taken centrally through the pipe. Fig. 2 is an elevation of the bowl and stem.' Fig. 3 is a top plan view of the rotatablepbowl ring. Fig. 4 is a transverse vertical section through the stem looking toward the bowl. Fig. 5 is a detail horizontal section taken on line 5 5 of Fig. 1. Fig. 6 is a top plan view of the rotatable tobacco receptacle. Fig. 7 is a bottom plan view of the ring j shown in Fig. 3. Fig. Sis a detail transverse section through the stem, taken on line 8-8 of Figyl, and, Fig. 9 is a similar view taken on line 9 9 of Fig. 2.

Referring now to these figures, the` bowl A is provided with the usual curved main stem Band mouthpiece C, and is also 'provided with a smoke stem D connecting the bowl adjacent its upper end with the upper end of the main stem B, the latter being without the usual smokepassage and having instead a groove b the o uter portion of which is covered by a curved cover plate B.

The bowl A is of a substantial length and has a deep opening or bore, the upper end of which is enlarged to provide an annular shoulder on which the annular ilange e of the tobacco chamber or receptacle E rests, the lower body ofl this receptacle being snugly though movably fitted. with the bore of the bowl..

Rising from a point intermediate the inner and outer edges of the flange e is the upper wall e of the receptacle E and resting upon the inner portion of the flange within this wall is the lower reduced edge of the rotatable bowl ring F, the upper portion of which is enlarged and seated on the upper end of bowl A. This ring is provided with a plurality of recesses f in its lower edge which receive projectionsl e2 of the fia'nge e and through which extend fastening members f (see dotted lines in Fig. 1)

for securing. the ring F to the receptacle E.

The rinfJr F is also provided with a circular series oi3 which are alined with similar openings through the upper receptacle wall e.

The receptacle E and ring F are held down in place by means of a split collar G surroundlng the wall e and resting on the outer edge of flange aand .secured to the bowl A by a fastener g and additionally held by a coil spring g bearing thereagainst and surrounding the mouth of the smoke tube H. which mouth or inner end` of said smoke tube extends through an opening in the sp1 it collar G and is adapted to register` with the several ring openings f2. To the end that an unobstructed smoke passage may lbe maintained at all times the ring F has a series of index marks f3 upon its upper surface above its openings f2, any one of which may be turned to a position centrally of the supplemental stem D in order to register a 'selected ring Opening f2 with the mouth of the smoke tube H, the latter extending through the supplemental stem and through transverse openings in the outer end of the main stem B and the lower reduced end of the mouthpiece C, thus locking the latter in position.

The outer end of the smoke tube H is closed by a screw cap or plug h which may be removed to provide for the introduction of any instrument for cleaning purposes.

In the receptacle Eis a vertically adjustable base E which may be easily adjusted by means of a slide arm I curved to tit and move longitudinally within the groove b of the main stem B, the inner camshaped end of this slide arm being extended beneath the base E. The outer end o'f the openings f2 adjacent its lower edge slide arm I has a knob or button c' projectingvthrough and working in a slot at one side of the cover plate B as shown in Fig.

4, and the intermediate portion of the arm of a curved spring I, the free end of which bears against the slide arm to hold the saine in adjusted position.

The mouth-piece C communicates with the smoke passage H through an opening 7L in the wall of the latter and thus with the parts in the position shown in dotted lines in Fig. l, the receptacle E may be filled andthe tobacco light-ed as in the ordinary pipe. As soon as the operation is well started, the quantity of smoke may be quickly and easily regulated and the consumption rendered uniform by rotating the ring F to desired points and the temperature may be controlled by raising or lowering the base E. These adjustments, it will be noted, may be readily and quickly made and the entire operation controlled to suit the needs or peculiar tastes of the user.

Itis to be further noted that the smoke is withdrawn from the bowl without necessitating its passage through the bulk of tobacco within the tobacco receptacle, thus eliminating in a great measure the production of nicotin.

I claim l. A tobacco pipe comprising a bowl, a curved main stern extending upwardly from the lower end of the bowl, a mouthpiece connected to the stem, a supplemental stem connecting the upper portions of the bowl and main stem and having a smoke passage communicating at one end with the bowl and at it-s opposite end with the mouthpiece, a rotatable tobacco receptacle within the bowl, a ring seated on the upper end of the bowl and connected to the receptacle, a vertically adjustable base within the receptacle, and a member slidably mounted in the main stem for adjust-ing the said base.

2. A tobacco pipe comprising a bowl, a curved main stem extending upwardly from the lower end of the bowl, a mouthpiece having its lower end extended into the upper end of the main stem, a supplemental stem connecting the upper ends of the main stem and bowl, said main stem and said mouthpiece having transverse alined openings, and a smoke tube extending through the supplemental stem and communicating at one end with the bowl and having its opposite end extending through the transverse openings of the main stem and mouthpiece, and provided with a wall opening communicating with the mouthpiece.

3. A tobacco pipe comprising a bowl, a

smoke stem communicating with the upper portion of the bowl, a mouthpiece communicating with the stem, a rotatable tobacco receptacle within the bowl and having a vertically adjustable base, a ring seated on the bowl and connected to the tobacco receptacle for rotating the latter, and means for adjusting the base.

4. A tobacco pipe comprising a bowl a smoke stem communicating with the upper portion of the bowl, a mouthpiece communieating with the stem, a rotatable tobacco receptacle within the bowl and having a plurality of points of communication with the smoke stem controlled by rotation of the receptacle, the bowl having a vertically adjustable base, and means for adjust-ing the base.

5. A tobacco pipe comprising a bowl, a curved main stem extending upwardly from the lower end of the bowl and having a groove the lower end of which extends centrally into the base of the bore of the bowl, a mouthpiece connected to the upper end of the stem, a supplemental stem connecting the upper portions of the bowl and the main stem and having a smoke passage communicating with the upper portion of the bore oli the bowl and the lower end of the mouthpiece, the bore of the bowl having an upper enlarged portion forming an intermediate annular shoulder, a tubular tobacco receptacle rotatable within the bowl bore and having an upper outwardly projecting flange seated on the said shoulder, a split clamping collar seated on the outer edge of the receptacle flange and secured to the bowl, a rotating ring seated on the upper end of the bowl and having a depending reduced portion secured fto the inner edge of the receptacle flange, said reduced ring port-ion also having a circular series ot' openings each of which may be positioned to register with the smoke passage, a base plate vertically adjustable within the tobacco receptacle, and an arm slidably mounted in the main stem groove and having an inner cam-shaped end beneath the base plate and an exterior projecting knob or handle upon its outer end, all for the purpose described.

MAURICE NEUMAN.
